Hi Zheng,
Many thanks for your helpful post, I've done the following:
1) set the threshold to 1024 * 1024:
# ceph config set osd \

2) deep scrubbed all of the pgs on the two OSD that reported "Large omap
object found." - these were all in p

Is the default of 200,000 too small? will this be adjusted in future
releases or is it meant to be adjusted in some use-ca
